So my buddy has Sins of a Solar Empire, and the Expansion (Entrenchment).  And one day when it updated it deleted it from his comp. Now his impulse has no "my games" or "my software" tabs, he cant reinstall Sins or Entr, but in the registration it says he has them, and it lists thier serial keys.  To boot, when he does the 'send me my cd key' thing where it sends the list of items you bought through impulse, it says he has nothing. So then why are they registered to him? and how does he go about reinstalling them?
